In a Nov. 6, 2006 file photo actor Michael J. Fox greets supporters at a rally for Wisconsin Gov. Jim Doyle in Milwaukee. On his upcoming NBC comedy, Fox will play a newscaster who quits his job because of Parkinson's Disease but returns to work in the show's first episode because a new medical regimen has helped him control many of the disease's symptoms. NBC said Sunday, Jan. 6, 2013, his comedy closely tracks many aspects of Fox's personal life and tries to have fun with an image that has left him an object of pity-fueled admiration.
